TEC-1000 Second Harmonic Generation - Jaguar
US Patent 5,867,512 | US Patent 6,297,066 | US Patent 6,869,483 | US Patents pendingDescription:
A resonant cavity including a frequency doubler crystal is pumped via a tunable diode laser. Depending on the required SHG power, the tunable diode laser is either a high power external cavity laser, or a two stage Master Oscillator Power Amplifier System. The covered wavelength regime ranges from 365nm up to 540nm.
High optical power
-
up to 500mW at 480nm available
-
system suitable for Fourth Harmonic Generation into the deep UV regime
-
linewidth < 1MHz -
excellent side mode suppression > 50dB
-
Bow-Tie type of resonant doubling cavity -
Sacher Littrow or Sacher Littman/Metcalf type of master lasers
-
large mode-hop free tuning range of up to 30GHz
-
Hänsch-Couillaud type of Locking of the resonant doubling cavity to the pump laser -
pump laser can be stabilized to atomic references via Side of Fringe or Pound Drever Hall
-
automated piezo tuning with power read-out -
remote control via GPIB, RS232 and USB
Configuration:
How it works:
Second harmonic generation exploits nonlinear features of certain materials which lead to a generation of doubled frequency. An easy-to-understand way of explaining is that two photons are absorbed whereas only one is emitted, which then carries the double energy and thus is at double frequency.
For different wavelengths, different material has to be used. Therefore, every system is tailored to the individual customer.
Optical cavity:
The use of an optical cavity is paramount for SHG generation since the nonlinear conversion efficiency is generally low. Therefore, the pump power is enhanced by using an optical cavity which is locked to the pump laser source. The locking mechanism is the Hänsch-Couillaud locking, which allows for modulation free stabilization of the cavity to the pump laser.
